為樹莓派配置dhcp伺服器（isc-dhcp-server），啟動服務時出現：
Job for isc-dhcp-server.service failed. See 'systemctl status isc-dhcp-server.service' and 'journalctl -xn' for details.
執行
# systemctl status isc-dhcp-server.service
得到
● isc-dhcp-server.service - LSB: DHCP server

很明顯，interface裝置錯了，被設定為了usb0
解決：
# vi /etc/default/isc-dhcp-server
修改預設的裝置（eth0, wlan0 ....)
